The Duke turned back and realized that Vivian had arrived at some point and was standing there, seemingly watching for a while.
He realized he had been a bit careless, letting his guard down because he was in the manor.

Vivian was still dressed in full armor, but she didn't have her giant axe, only a delicate longsword at her waist.
"Miss Vivian!" The Duke placed his right hand over his heart in salute.
Vivian walked over and said, "I initially taught you this combat skill on a whim, wanting to see your potential. I didn't expect much, but I'm surprised you managed to train to this level. How's your progress with the breathing technique?"
"I've recently reached the fifth level of the breathing technique," the Duke said.
